@ -18,6 +18,8 @@ Key features in Loki 3.3.0 include the following:
- **Explore Logs:** Starting with Grafana v11.3, the plugin for the Explore Logs app is installed in Grafana by default. This release includes enhancements to improve pattern ingester tracing ([#14707](https://github.com/grafana/loki/issues/14707)) ([80aec25](https://github.com/grafana/loki/commit/80aec2548203957dbb834ba69e6d734d9054416d)), to apply patterns line length limit to json message keys ([#14296](https://github.com/grafana/loki/issues/14296)) ([41fafd8](https://github.com/grafana/loki/commit/41fafd87933224d5d43592e91e339322fc90a466)), add configuration to set `max-allowed-line-length` in the pattern ingester ([#14070](https://github.com/grafana/loki/issues/14070)) ([0780456](https://github.com/grafana/loki/commit/0780456662b67edde69004cf4ee3873c23d5094b)) and move metric aggregation to a per-tenant configuration ([#14709](https://github.com/grafana/loki/issues/14709)) ([c1fde26](https://github.com/grafana/loki/commit/c1fde26730b4fc54e4bbc724d1b29f653541f720)).
- **logql:** We've added an `approx_topk` function to LogQL, which uses probabilistic techniques to give you an approximation of the most frequent values in the input, along with their approximate frequencies. This is great for cases where the equivalent `topk` query hits the maximum series limit or times out before completion. Its also great in cases where you want a faster response to your query and are fine with an approximation of the true answer. ([#14243](https://github.com/grafana/loki/issues/14243)). For more information, visit [LogQL docs](https://grafana.com/docs/loki/latest/query/metric_queries/#probabilistic-aggregation).
